About WITTENSTEIN

Reliable electric actuators and mechatronic systems for the subsea oil and gas industry

WITTENSTEIN motion control develops both customer-specific electric actuation subsea drive systems and subsea electric actuators for use in water depths up to and beyond 3000 meters.

The subsea electric actuation systems and subsea electric actuators set standards in reliability and durability. We integrate state of the art subsea electric actuation solutions for subsea processing, production and special applications.

Our systems are developed according to the requirements of ISO 61508. The customer’s systems are therefore capable of being SIL-certified. Using our proven dual-channel subsea electric actuator, the customer’s system can achieve a safety integrity level of up to SIL 3.

SPECIALISTS IN EXTREME CONDITIONS

SPECIALISTS IN EXTREME CONDITIONS

We have many years of experience in developing solutions for the oil and gas sector.

Our fully qualified subsea electric actuator program have been used reliably on the seabed for more than 15 years. Production and assembly of our high availability electric actuators is based on tried and tested manufacturing processes. The WITTENSTEIN subsea actuators are especially compact and light weight – a great advantage when space is at a premium. Our systems are maintenance-free as well as being simple and intuitive to handle. With standard open communication interfaces, they offer fast deployment and ease of set up. Sea depths up to and beyond 3000 meters see the deployment of our high reliability, high availability precision and dynamic subsea actuators. The SSEAC® subsea electric actuators which are more compact, effective and environmentally friendly than traditional hydraulic solutions are the way to enhance oil and gas recovery, reduce environmental impact and allow access to deeper waters for development.

The qualification is implemented according to the ISO 13628-6 Stage Q2 specification or other guidelines (Statoil TR among others). Here, EMC guidelines as well as pressure and sealing requirements are examined. The qualification program may also be designed and implemented according to project specific requirements.

OPENING UP NEW OIL FIELDS AND WELLS

OPENING UP NEW OIL FIELDS AND WELLS

Extraction of fossil fuels is becoming increasingly more difficult to access offshore with deeper water and harsh environmental conditions becoming the norm. With our new technologies WITTENSTEIN creates new opportunities, where it has previously been uneconomical to extract.

The result: increased production rates, maximized yields and reduced costs: Since 2001, more than 250 of our customer-specific electric actuator drive systems have been in use on the UK and Norwegian continental shelf, as well as in Brazilian and Australian waters.

SOLUTIONS FOR DIRECTIONAL DRILLING

SOLUTIONS FOR DIRECTIONAL DRILLING

WITTENSTEIN’s high temperature motor and gear systems help Oil and Gas well directional drilling programs to improve the rate of penetration (ROP).

Since 2001, more than 2000 of our systems have been used in drill head control. They are characterized by their extreme durability in combination with high functional reliability and low maintenance.

We have enhanced Tractor Systems, Measurement While Drilling systems and Downhole Power Generation Systems with our HT/HP Systems. With our unique range of production capacities and in-house tests, we are positioned to offer customized high temperature and high pressure (HT/HP) motors and gear systems to our customers. Development, design, detailed calculations, load testing and product optimization are optimally interlinked.

During dimensioning, design and measurement and test phases, the unique expertise of our specialist engineers comes into play. We are constantly developing our solutions. The close contact between colleges and research institutes guarantees that we are at the forefront of technology. We subject all our systems to a complete test cycle. This includes a technical test, factory acceptance test and environmental stress screening as well as performance and load testing.
